For any surface of any lens, the profile curve length within theeffective half diameter affects the ability of the surface to correctaberration and differences between optical paths of light in differentfields of view. With longer profile curve length, the ability to correctaberration is better. However, the difficulty of manufacturing increasesas well. Therefore, the profile curve length within the effective halfdiameter of any surface of any lens has to be controlled. The ratiobetween the profile curve length (ARS) within the effective halfdiameter of one surface and the thickness (TP) of the lens, which thesurface belonged to, on the optical axis (i.e., ARS/TP) has to beparticularly controlled. For example, the profile curve length of themaximum effective half diameter of the object-side surface of the firstlens is denoted by ARS11, the thickness of the first lens on the opticalaxis is TP1, and the ratio between these two parameters is ARS11/TP1;the profile curve length of the maximum effective half diameter of theimage-side surface of the first lens is denoted by ARS12, and the ratiobetween ARS12 and TP1 is ARS12/TP1. The profile curve length of themaximum effective half diameter of the object-side surface of the secondlens is denoted by ARS21, the thickness of the second lens on theoptical axis is TP2, and the ratio between these two parameters isARS21/TP2; the profile curve length of the maximum effective halfdiameter of the image-side surface of the second lens is denoted byARS22, and the ratio between ARS22 and TP2 is ARS22/TP2. For any surfaceof other lenses in the optical image capturing system, the ratio betweenthe profile curve length of the maximum effective half diameter thereofand the thickness of the lens which the surface belonged to is denotedin the same manner.

For any surface of any lens, the profile curve length within a half ofthe entrance pupil diameter (HEP) affects the ability of the surface tocorrect aberration and differences between optical paths of light indifferent fields of view. With longer profile curve length, the abilityto correct aberration is better. However, the difficulty ofmanufacturing increases as well. Therefore, the profile curve lengthwithin a half of the entrance pupil diameter (HEP) of any surface of anylens has to be controlled. The ratio between the profile curve length(ARE) within a half of the entrance pupil diameter (HEP) of one surfaceand the thickness (TP) of the lens, which the surface belonged to, onthe optical axis (i.e., ARE/TP) has to be particularly controlled. Forexample, the profile curve length of a half of the entrance pupildiameter (HEP) of the object-side surface of the first lens is denotedby ARE11, the thickness of the first lens on the optical axis is TP1,and the ratio between these two parameters is ARE11/TP1; the profilecurve length of a half of the entrance pupil diameter (HEP) of theimage-side surface of the first lens is denoted by ARE12, and the ratiobetween ARE12 and TP1 is ARE12/TP1. The profile curve length of a halfof the entrance pupil diameter (HEP) of the object-side surface of thesecond lens is denoted by ARE21, the thickness of the second lens on theoptical axis is TP2, and the ratio between these two parameters isARE21/TP2; the profile curve length of a half of the entrance pupildiameter (HEP) of the image-side surface of the second lens is denotedby ARE22, and the ratio between ARE22 and TP2 is ARE22/TP2. For anysurface of other lenses in the optical image capturing system, the ratiobetween the profile curve length of a half of the entrance pupildiameter (HEP) thereof and the thickness of the lens which the surfacebelonged to is denoted in the same manner.

In an embodiment, a height of the optical image capturing system (HOS)can be reduced while |f1|>f5.

In an embodiment, when |f2|+|f3|+|f4| and |f1|+|f5| of the lensessatisfy the aforementioned conditions, at least one lens among thesecond to the fourth lenses could have weak positive refractive power orweak negative refractive power. Herein the weak refractive power meansthe absolute value of the focal length of one specific lens is greaterthan 10. When at least one lens among the second to the fourth lenseshas weak positive refractive power, it may share the positive refractivepower of the first lens, and on the contrary, when at least one lensamong the second to the fourth lenses has weak negative refractivepower, it may fine turn and correct the aberration of the system.

In an embodiment, the fifth lens could have negative refractive power,and an image-side surface thereof is concave, it may reduce back focallength and size. Besides, the fifth lens can have at least an inflectionpoint on at least a surface thereof, which may reduce an incident angleof the light of an off-axis field of view and correct the aberration ofthe off-axis field of view.

In an embodiment, the lenses of high Abbe number and the lenses of lowAbbe number are arranged in an interlaced arrangement that could behelpful for correction of aberration of the system.

An equation of aspheric surface is

z=ch ²/[1+[1(k+1)c ² h ²]^(0.5) ]+A4h ⁴ +A6h ⁶ +A8h ⁸ +A10h ¹⁰ +A12h ¹²+A14h ¹⁴ +A16h ¹⁶ +A18h ¹⁸ +A20h ²⁰+ . . .  (1)

where z is a depression of the aspheric surface; k is conic constant; cis reciprocal of the radius of curvature; and A4, A6, A8, A10, A12, A14,A16, A18, and A20 are high-order aspheric coefficients.

In the optical image capturing system, the lenses could be made ofplastic or glass. The plastic lenses may reduce the weight and lower thecost of the system, and the glass lenses may control the thermal effectand enlarge the space for arrangement of the refractive power of thesystem. In addition, the opposite surfaces (object-side surface andimage-side surface) of the first to the fifth lenses could be asphericthat can obtain more control parameters to reduce aberration. The numberof aspheric glass lenses could be less than the conventional sphericalglass lenses, which is helpful for reduction of the height of thesystem.

When the lens has a convex surface, which means that the surface isconvex around a position, through which the optical axis passes, andwhen the lens has a concave surface, which means that the surface isconcave around a position, through which the optical axis passes.

The optical image capturing system of the present invention could beapplied in a dynamic focusing optical system. It is superior in thecorrection of aberration and high imaging quality so that it could beallied in lots of fields.

The optical image capturing system of the present invention couldfurther include a driving module to meet different demands, wherein thedriving module can be coupled with the lenses to move the lenses. Thedriving module can be a voice coil motor (VCM), which is used to movethe lens for focusing, or can be an optical image stabilization (OIS)component, which is used to lower the possibility of having the problemof image blurring which is caused by subtle movements of the lens whileshooting.

To meet different requirements, at least one lens among the first lensto the fifth lens of the optical image capturing system of the presentinvention can be a light filter, which filters out light of wavelengthshorter than 500 nm. Such effect can be achieved by coating on at leastone surface of the lens, or by using materials capable of filtering outshort waves to make the lens.

To meet different requirements, the image plane of the optical imagecapturing system in the present invention can be either flat or curved.If the image plane is curved (e.g., a sphere with a radius ofcurvature), the incidence angle required for focusing light on the imageplane can be decreased, which is not only helpful to shorten the lengthof the system (TTL), but also helpful to increase the relativeilluminance.

An object-side surface 222 thereof, which faces the objectside, is a convex aspheric surface, and an image-side surface 224thereof, which faces the image side, is a concave aspheric surface. Theobject-side surface 222 and the image-side surface 224 both have aninflection point.

The third lens 230 has negative refractive power and is made of plastic.An object-side surface 232, which faces the object side, is a convexaspheric surface, and an image-side surface 234, which faces the imageside, is a concave aspheric surface. The object-side surface 232 has aninflection point, and the image-side surface 234 has two inflectionpoints.

The fourth lens 240 has positive refractive power and is made ofplastic. An object-side surface 242, which faces the object side, is aconvex aspheric surface, and an image-side surface 244, which faces theimage side, is a convex aspheric surface.
